Posted day will arrive tomorrow Prog, sorry for the delay

anyone know what the difference is if any between the Carbon copy & the Malekko 600?

Post by **Mike** » Thu Jun 11, 2009 8:34 pm

They're both analogue, I dunno whether the Malekko has modulation though?

They both have 600ms. Malekko is loads more expensive...

no worries mike, i'm off tomorrow so it means i can play with it all day. and the delay too

pedal arrived today, thanks mike. so far, i'm liking it. very warm sounding, almost chorus like on short settings. it's a short delay, though have found out you can lengthen it a little using the internal trim pot.

i've had a play around with the internal trim pot. i've not touched the two orange ones at the top, have no idea what they do. the black one to the left of the rate control adjusts the delay time. you can get to around 400ms with this at max, but it becomes more lo-fi, kinda like a low quality MP3.

Yeah don't touch the orange ones, those are setting up the Analogue Delay chips and need to be set with a 'scope.

Mike, how come these trimmers need to be set up using an oscilloscope rather than "by ear" (I guess in the same way those on a DMM does)? What's the difference?

Because you're dealing with acute setup of the delay chips, the clocking into them, noise suppression etc. It's something you can half-arse if you go about it in a set way but it's really not a good idea. The best thing to do is to use a 'scope and inject a sine wave into it and calibrate from there. This is pretty much standard for all analogue delays.

as Howard Davis, designer of the EHX DMM explains:

Guitar effects pedals containing analog delay chips, and a few other types of components, have internal trimpots for adjustment by a technician. For proper operation these must be correctly set, and this is done at the factory. In time - especially with the rough handling that guitar pedals are often subject to - these trimpots can become misadjusted, resulting in distortion, improper operation, or no operation at all.

It is virtually impossible to correctly adjust all the trimpots - called "doing an alignment" - without using lab equipment and the proper procedure. An audio oscillator, oscilloscope, the schematic, PC board diagram, and the test and alignment procedure for that particular pedal are required, as well as technical training and experience. Attempting an alignment without these essentials usually just makes the problem worse - and sometimes more costly to fix!

The most common symptom indicating the need for an alignment is overdrive distortion occurring at too low a signal level. This can also result from weak batteries or an abnormally low power supply voltage, so make sure to check this before sending your pedal for repair.

i'm leaving the orange one's well alone. i've set the internal back to stock, as it's very rare i'd need longer. if i did, i'd just whack out the dd-3

I've been using my DD-3 alongside the PB&J (FUCKING.LOVE.THIS. THING) sounds awesome and i guess kinda analogue like. Wonder how the Vintage delay and dd-3 sound used together.

glad it got there ok. what you liking so far?

might dig out the dd-3 and whack it on the board for a play around

The delay side with the green led is my favourite, not sure if thats the long/short one though. These are discontinued right?

yes, they've not been around for some time now. don't know why, it's a pretty good delay. green is the longer delay and it set to this by default. it's weird as i knew someone that had one and his was set to short by default.
